I'm building a Tumblr site and I want that when a user clicks on the tags span, it should display the tags. It was working properly until today, and now when you click on, it comes back immediately. I can't figure out what is wrong.
HTML
<span class="tags-link">Tags</span>
{block:HasTags}
<ul class="tags tags-close">
{block:Tags}
<li>
{Tag}
</li>
{/block:Tags}
</ul>
{/block:HasTags}
CSS
.tags{
list-style-type: none;
padding: 0;
margin: 24px 0 0 0;
}
.tags-open{
display: block;
}
.tags li{
font-size: 14px;
}
.tags li a{
color: #9CA8B3;
margin-right: 12px;
}
.tags-close{
display: none;
}
jQuery
$(document).ready(function(){
$(".tags-link").click(function() {
$(this).next(".tags").slideToggle(500, function(){
$(this).toggleClass("tags-open");
$(".tags li").css("display","inline-block");
//end animation
});
}); // end tags
}); // end ready
try using .toggle() instead, i believe through JQuery UI you can achieve the slide effect.
$(document).click(function(){
var tags = $(this).next('.tags');
tags.toggle('slide', {direction:'up'},500);
$(this).animate(500).toggleClass("tags-open"); //animate fades class changes
$("li.tags").animate(500).css("display","inline-block");
});

I am working with a CMS. In order to show some list content I need a count on the list items to spread them evenly over the page. I did this function:
$(document).ready(function() {
$("button").click(function() {
var count = $("#page_menu ul li").length;
var breit = 945 / count;
$("#page_menu li").css("width", breit);
})
})
#page_menu ul {
margin: 0px;
top: 0px;
}
#page_menu li {
border: 1px solid #fff;
margin: 0 -1px 0 0;
display: flex;
justify-content: center;
text-align: center;
align-items: center;
}
#page_menu ul li {
height: 50px;
float: left;
list-style: none;
font-size: 13px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="page_menu">
<ul class="nav menu mod-list">
<li class="item-121"><a href="/index.php/about/querfloete" >Querflöte</li><li class="item-123"><a href="/index.php/about/autor" >Autor</li></ul>
</div>
<button>change</button>
This does exactly what it is supposed to do - TOO LATE!
To be precise: The page loads and builds the list. The javascript afterwards performs its counting function and releases it to the CSS. However, by then the CSS relating to the list doesn't get the information anymore. The button stays blank and without function regardless if it was placed before the javascript section or after. And it stays that way until I go a level down in the submenu with the same menu. Then it works fine.
And the other thing is, that I would like to load it by itself and not via clicking a button. How can I achieve this?
Sorry, I haven't been working this kind of stuff for the past 10 yrs. I am completely somewhat lost.
I'm relatively new to jQuery, and I'm experiencing some trouble with it. My assignment is to redesign a webpage and implement certain features using jQuery. Right now, I'm trying to create a dropdown menu for each "button" in my nav bar. When I hover over a "button" in the nav bar, a dropdown menu should show up. My jQuery appears to be working but the dropdown menu isn't showing up on the webpage...
Here is my code:
<head>
<title>Team Imperial College: Project Description</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="js/main.js"></script>
<link rel="stylesheet" href="styles/normalize.css" type="text/css"/>
<link rel="stylesheet" href="styles/styles.css" type="text/css"/>
</head>
Here is the HTML code (nav bar and dropdown menu code):
<ul class="nav_bar">
<li class="dropdown">
Our Team
<ul class="dropdown_content">
<li>Meet the Team</li>
<li>Attributes</li>
</ul>
</li>
<li>Our Project</li>
<li>
Modelling
</li>
<li>Software</li>
<li>
Documentation
</li>
<li>
Human Centered Design
</li>
</ul>
Here is my CSS code:
html, body {
margin: 0;
padding: 0;
font-family: 'Raleway', sans-serif;
background-color: #EDDBDB;
}
.nav_bar {
position: fixed;
top: 0px;
width: 100%;
list-style-type: none;
margin: 0;
padding: 0;
background-color: #F3F3FF;
overflow: hidden;
}
.nav_bar li {
float: left;
}
li a {
display: block;
color: #000000;
text-align: center;
padding: 24px 20px;
text-decoration: none;
font-size: 105%;
}
/*dropdown menu code*/
.dropdown {
position: relative;
display: inline-block;
}
.dropdown_content {
display: none;
position: absolute;
background-color: #F3F3FF;
min-width: 160px;
z-index: 1;
}
.dropdown_content li a {
color: #000000;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown_content li a:hover {
background-color: #DBDBE5;
}
.dropdown:hover .dropdown_content {
display: block;
}
/dropdown menu code/
And here is my jQuery code:
$(document).ready(function() {
$('.dropdown').hover(function() {
$('.dropdown_content').toggle();
});
$('.dropdown_content li a').hover();
});
Please help! Help will be greatly appreciated, thanks!
First test i would make is make dropdown_content visible since begin, to make sure the toggle function works.
Then you can do this test:
$('.dropdown').hover(function() {
$('.dropdown_content').toggle();
alert('Over here');
});
Check how many times "Over here" appears.
Having those answers will help you on the way out of this.
if (jQuery) {
alert(“jquery is loaded”);
} else {
alert(” Not loaded”);
}
it seems you haven't addressed the event on mouse out. try changing this code:
$('.dropdown').hover(function() {
$('.dropdown_content').toggle();
});
to this:
$('.dropdown').hover(function() {
$('.dropdown_content').toggle();
}, function() {
$('.dropdown_content').toggle();
});
if you want it only to be trigger on when entering it do this:
$('.dropdown').mouseenter(function() {
$('.dropdown_content').toggle();
});
i suggest looking at this for better detail.
EDIT:
how toggle works is by making the element's display variable to none that essentially means that it does not exist on the page anymore.
if you wanted it to toggle on hover, you would need to toggle the opacity between 0 and 1.
best method:
create a css class
.hidden {
opacity: 0;
}
edit JQuery code
$(document).ready(function() {
$('.dropdown').hover(function() {
$('.dropdown').toggleClass('.dropdown', "hidden");
//you can use this for multiple elements
//$(this).toggleClass(this, "hidden");
});
$('.dropdown_content li a').hover();
});
deprecated method:
$(document).ready(function() {
$('.dropdown').hover(function() {
$('.dropdown_content').toggle(() => {
$('.dropdown_content').css({opacity: "0"});
}, () => {
$('.dropdown_content').css({opacity: "1"});
});
});
$('.dropdown_content li a').hover();
});
note: () => {} is shorthand for a callback function
I've got a working jQuery script that runs ok meaning it serves its purpose.
The question is: how to make this script more efficient?
Currently the script becomes active the moment a user places the mouse over (hover) a certain HTML5 section-tag with an ID. At this moment the script removes the existing class named 'noDisplay' from a subordinate nav-tag containing a submenu list, hence content becomes visible to the user. This submenu list may be three to four levels deep. The submenus are held in classes (subMenu1, subMenu2, subMenu3, subMenu4, etc.).
The script is written to serve individually each of the given section IDs and its sublevel classes.
Basically the script interacts with the DOM by removing the class 'noDisplay' upon mouse hover and restores the same class upon mouse leave.
(Tried to give a clear explanation. If not please ask.)
Here is a JSfiddle: enter link description here
I hope someone can suggest a way to do this much more efficiently.
Possibly with more sections (#ID's) and subMenu-levels (a class per level).
Using the CSS properties 'display: none;' and 'display:block;' would be the simplest solution but this is not desired because a search-bot my decide to skip content flagged as invisible to the user or a screenreader. The class 'NoDisplay' in use here keeps content invisible to users and keeps its readability to screen readers (and thus to most of the search bots).
So basically the script function remains as is to remove and add the class 'noDisplay' upon hover.
The goal is to obtain a script that is more efficient that could use for instance variables for each section, instead of writing code for each new section and hence extending the current script.
//section1$("#section1 .NavUL1 .subMenu1").hover(function(){
$(".NavUL2").removeClass("noDisplay"); //display
},function(){
$(".NavUL2").addClass("noDisplay"); //no display
});
$("#section1").hover(function(){
$("#section1 .NavUL1").removeClass("noDisplay"); //display
},function(){
$("#section1 .NavUL1").addClass("noDisplay"); //no display
});
$("#section1 .NavUL1 .subMenu1").hover(function(){
$(".NavUL2").removeClass("noDisplay"); //display
},function(){
$(".NavUL2").addClass("noDisplay"); //no display
});
//#section2
$("#section2").hover(function(){
$("#section2 .NavUL1").removeClass("noDisplay"); //display
},function(){
$("#section2 .NavUL1").addClass("noDisplay"); //no display
});
$("#section2 .subMenu1").hover(function(){
$(".subMenu1 .NavUL2").removeClass("noDisplay"); //display
},function(){
$(".subMenu1 .NavUL2").addClass("noDisplay"); //no display
});
$("#section2 .subMenu2").hover(function(){
$(".subMenu2 .NavUL2").removeClass("noDisplay"); //display
},function(){
$(".subMenu2 .NavUL2").addClass("noDisplay"); //no display
});
$("#section2 .subMenu3").hover(function(){
$(".subMenu3 .NavUL2").removeClass("noDisplay"); //display
},function(){
$(".subMenu3 .NavUL2").addClass("noDisplay"); //no display
});
$("#section2 .subMenu4").hover(function(){
$(".subMenu4 .NavUL2").removeClass("noDisplay"); //display
},function(){
$(".subMenu4 .NavUL2").addClass("noDisplay"); //no display
});
My suggestion would be to create a new class, call it whatever but for demonstrative purposes we'll call it hover-class
Then it becomes simple:
$('.hover-class').hover(
function() { $(this).addClass('noDisplay'); },
function() { $(this).removeClass('noDisplay'); }
);
I'd recommend just using CSS, there shouldn't be a need for JS:
nav ul{
position: absolute;
border: 1px solid #444444;
box-shadow: 8px 8px 11px #222222;
background: #888;
padding: 0.5em 0.5em 0.5em 0em;
list-style-type: none;
margin-left: 15%;
display: none;
}
.sectionBox:hover nav > ul, nav li:hover > ul {
display: block;
}
This does away with all the IDs and classes while keeping the same effect. You html looks like this now (just a snippet):
<ul>
<li><h2>various whatever1</h2></li>
<li>link11</li>
<li>link12</li>
<li>link13</li>
<li>link14</li>
<li><h2>sub1</h2>
<ul>
<li>sub1-link11</li>
<li>sub1-link12</li>
<li>sub1-link13</li>
<li>sub1-link14</li>
</ul>
</li>
</ul>
Here it is working: http://jsfiddle.net/VGXNz/1/
Update:
If you want to use your original noDisplay styles then this would be the CSS:
nav ul{
position:absolute;
border: 0;
clip: rect(0 0 0 0);
width: 1px;
height: 1px;
margin: -1px;
overflow: hidden;
padding: 0;
}
.sectionBox:hover nav > ul, nav li:hover > ul{
height: auto;
width: auto;
margin: 0 0 0 15%;
border:1px solid #444444;
box-shadow:8px 8px 11px #222222;
background:#888;
padding:0.5em 0.5em 0.5em 0em;
list-style-type:none;
clip: auto;
overflow: visible;
}
Here's a fiddle: http://jsfiddle.net/KKmVU/1/
why would you use js in the first place? Css is perfectly capable of handling hover states, and IMO you should always go for the css solution if there is one.
I made some quick (and dirty) changes to your fiddle:http://jsfiddle.net/3epRN/1/
I removed a bunch of classes and id's from the markup, removed all js, and tweaked the css a bit. The relevant css looks like this:
.sectionBox nav {
display: none;
}
.sectionBox:hover nav {
display: block;
position: absolute;
top: 90%;
left: 50px;
background-color:#646464;
z-index: 5;
}
.sectionBox nav ul ul {
display: none;
}
.sectionBox nav ul li {
position: relative;
}
.sectionBox nav ul li:hover ul {
display: block;
position: absolute;
top: 0;
left: 80%;
background-color:#646464;
z-index: 5;
}
Obviously this needs some finetuning, but I'm sure you get the idea...
edit
I must admit I missed the part about the display:none beeing a problem for you. I do have to say I disagree with your arguments as to why (it is used al over the net, and crawlers and screen readers are smart enough nowadays).
That beeing said, nothing prevents you to use the css styling you now use to hide content (by adding the noDisplay class) directly in your css where I used the display:none;, and countering it when you want to display content by adding the following in stead of an ordinary display:block:
height: auto;
width: auto;
clip: auto;
overflow: visible;
The result would be identical to your js solution. I updated my fiddle to demonstrate:
http://jsfiddle.net/3epRN/2/
I am having trouble with a navigation menu I have created. Basically, the navigation consists of several tabs that is collapsible upon click a button and then expandable when you click that button again. When collapsed, the ends of the tabs are still visible, and when you hover over the tabs will go back out, and go back in when hovering out.
So I have the following navigation laid out:
<ul id="navigation">
<li>Name1</li>
<li>Name2</li>
<li>Name3</li>
<li id = "collapser">Collapse All</li>
</ul>
And I have the following jQuery/javascript laid out to do this:
$("#collapser").click(function(){
if($("#collapser").hasClass("clicked")){
$(function() {
$('#navigation a').stop().animate({'marginLeft':'-118px'},1000);
$('#navigation > li').hover(
function () {
$('a',$(this)).stop().animate({'marginLeft':'0px'},400);
},
function () {
$('a',$(this)).stop().animate({'marginLeft':'-118px'},400);
}
);
});
$("#collapser").removeClass("clicked");
$("#collapser").addClass("unclicked");
$("#collapser").html('Expand All')
}
else{
$(function() {
$('#navigation a').stop().animate({'marginLeft':'0px'},1000);
$('#navigation > li').hover(
function () {
$('a',$(this)).stop().animate({'marginLeft':'0px'},400);
},
function () {
$('a',$(this)).stop().animate({'marginLeft':'0px'},400);
}
);
});
$("#collapser").removeClass("unclicked");
$("#collapser").addClass("clicked");
$("#collapser").html('Collapse All')
}
})
The code works, but only when you click the link a second time. I can't seem to figure out what I did to make it work only after clicking it once already.
Any help would be appreciated, thank you very much!!

EDIT:
Here is the CSS for the navigation:
ul#navigation {
position: fixed;
margin: 0px;
padding: 0px;
font-size:14px;
top: 14px;
left: 0px;
list-style: none;
z-index:9999;}
ul#navigation li {
width: 100px;
}
ul#navigation li a {
display:block;
margin-bottom:3px;
width:126px;
padding:3px;
padding-left:15px;
background-color:#ffffff;
background-repeat:no-repeat;
background-position:center center;
opacity:0.7;
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=60);
-moz-box-shadow: 0px 1px 3px #000;
-webkit-box-shadow: 0px 1px 3px #000;
}
ul#navigation .checked a{
color:#ffffff;
background-color:#000000;
}
You are verifying if your collapser div has or not the class clicked or unclicked, but you not initialize the div with some class. Adding the class clicked should adjust your effect:
<li id = "collapser" class='clicked'>Collapse All</li>
You can see it with this jsfiddle
I am starting a Jquery drop down menu for a new project and it is working as expected on Google Chrome, Firefox, Safari but of course it is giving me some headache on Internet Explorer.
here's the thing,
See this page
http://www.universidadedoingles.com.br/dev/index.ASP
on mouse over the menu HOME, the drop down appers, when you move over the links in IE you see some flashes of the background, which doesn't happens on Chrome and ETC.
here's the js coda I am using to do the dd menu.
<script type="text/javascript">
$(document).ready(function() {
$("ul.mainmenu li.menuhome").mouseover(function(){
$(".arrow-spacer").show(); //When mouse over ...
//Following event is applied to the subnav itself (making height of subnav 150px)
$(this).find('.submenu').show().animate({height: '150px', opacity:'1'},{queue:false, duration:300})
});
$("ul.mainmenu li.menuhome").mouseout(function(){ //When mouse out ...
//Following event is applied to the subnav itself (making height of subnav 0px)
$(this).find('.submenu').hide().animate({height:'0px', opacity:'0'},{queue:false, duration:200})
});
//menu itembackground color animation
$("li").hover(function() {
$(this).animate();},
function() {
$(".arrow-spacer").hide();
});
});
</script>
That's it, I guess it may be simple, but it's been weeks and I still can't get it to work.
Thanks a lot.
I noticed that the anchor <a> tags have a margin on them. My first thing would be to try using padding instead. IE doesn't treat a hover in the margin the same way as other browsers.
in some cases it helps to set a z-index on elements that should placed in top of other elements.
In your case I would try to set the z-index on <ul class="submenu">
No blinks anymore! I changed one word hide() to stop (), now there is no blinking on iE. but...
After you show the menu 1 time, everytime you get your mouse below the link or close the link, the menu shows up again.
check this
www.universidadedoingles.com.br/dev
you'll be able to see its behavior
The thing is that the focus to <li> is lost when you mouse over an <a> element.
Here is something you could use to overcome this. I avoided using the <a> tag, instead I used a JavaScript function to send the user to the preferred location. I used JavaScript rather than jQuery hoping to make it more self-explanatory.
<script type="text/javascript" src="jquery.js" ></script>
<script type='text/javascript'>
$(document).ready(function() {
$('#n li').hover(function() {
$('ul', this).slideDown(200);
$(this).children('a:first').addClass('h');
}, function() {
$('ul', this).slideUp(200);
$(this).children('a:first').removeClass('h');
});
});
